obama in 2008. he says the young throngs have changed in attitude, but they're not less inspired. what i've seen is that there is a realization that changes, not a light switch. if it was easy to flip on light switch and change everything, somebody would have done it before. it's a very laborious process. it's very slow. i would say it's not disillusionment, it's understanding the process. >> reporter: a lot of hollywood actors, i don't mean that in a derogatory way, a lot of hollywood actor appear at rallies. you're the only one i ever heard of who has then taken a job, and a behind the scenes job really with the administration. what could possibly motivate you to do that? >> i have friends and folks who i knew over in iraq and afghanistan. i had buddies who had huge student debt, people got kicked off their health insurance plans for one reason or another. that was my decision to get involved on a personal level.
